The invention discloses a copper strip cover annealing technology. The copper strip cover annealing technology comprises the following steps that a, a copper strip coil is placed in an annealing furnace, vacuumizing is conducted, and then nitrogen is charged; b, staged type heating is conducted on an inner cover through a heating cover, wherein in the first stage, heating is conducted at the heating rate of 120 DEG C/h until the temperature of the copper strip reaches 180 DEG C, and in the second stage, heating is conducted at the temperature raising rate of 75 DEG C/h until the temperature of the copper strip reaches 250 DEG C; c, after the copper strip is heated to the annealing temperature, the temperature is kept for 5 h; d, after temperature keeping is ended, the heating cover is replaced by a cooling cover, and the copper strip is cooled to 74 DEG C in the manners that air cooling is conducted firstly, and then water cooling is conducted, wherein in the air cooling stage, the rotation speed of a draught fan is 1100 r/min, and nitrogen is continuously fed into the furnace in the cooling stage; and e, after cooling is ended, the inner cover is opened, and discharging is conducted. By the adoption of the copper strip cover annealing technology, the technology steps are simplified, so that the annealing time is shortened, and the yield is improved.
